Vintage lights.

These lights have elements of cast iron, wheels and all sorts of materials, which in fact make them interesting designs I think. The simplicity of it is an advantage as well, the most difficult part is getting your hands on those cast iron mountings, you can salvage them in scrapyard-but good luck with that one-those guys sell them the minute they see an item like this. Best bet is to find it on ebay-not that cheap though, but then again-this will last forever and one day-so it is worth the money.

Couple other things you will need-is a nice wire/cord, one of those antique twisted braided woven silk fabric cable cord you can get on ebay in almost eny colour you wish. Do not make a mistake of using any cord- that can mess up the entire design.
